## Indications for use
For in vitro diagnostic use: Etest is a quantitative technique for the determination of antimicrobial susceptibility of both non-fastidious Gram negative and Gram positive aerobic bacteria, such as Enterobacteriaceae, Pseudomonas, Staphylococcus and Enterococcus species and fastidious bacteria, such as anaerobes, Pneumococcus and Haemophilus species. The system comprises a predefined antibiotic gradient which is used to determine the Minimum Inhibitory Concentration (MIC) in pg/ml of individual antibiotics against bacteria as-tested on agar media by overnight incubation. This Etest 510(k) application is for MIC determination of Grepafloxacin in the range of - 0.002 - 32 pg/ml with non-fastidious Gram negative and Gram positive aerobic bacteria, S. pneumoniae, H. influenzae and N. gonorrhoeae.
